Subject: CVE request: FreeBSD/NetBSD 802.11 kernel memory disclosure
NetBSD has committed a fix for an issue in the 802.11 stack [1].
FreeBSD is also affected and should release a fix shortly. Due to a
signedness error in the IEEE80211_IOC_CHANINFO ioctl, a local
unprivileged user could cause the kernel to copy large amounts of
kernel memory back to the user, disclosing potentially sensitive
information. The issue only affects certain non-x86 architectures,
such as SPARC.
